Facebook timeout problems

This last days I had annoying facebook problems. It had to do that my facebook account would drop me out after a view seconds and I would have to login every time I went to another page. After restating the browser, deleting all cookies, reseting the browser etc. I figured out that the problem came from the chat program in facebook. I use Adium, a chat program that connects the different chat accounts I have, like msn, ichat and facebook. It seems like if I have Adium and facebook open at the same time facebook logs me out after a view seconds. I guess some seriuos bugs in the facebook software or security issues with a third party software like Adium. To avoid this I cannot be loged into facebook and Adium at the same time.
